When Martha Carlin learned about her husband´s Parkinson’s Disease (PD) diagnosis, she also realized that there were links between chronic disease and diet, stress and environment and became fascinated about the human microbiome. At TEDxBoulder, held in September 2016 in Boulder, Colorado (US), Carlin offered a talk where she pointed at our poop as the possible answer to Parkinson’s disease and many other chronic diseases.
